अग्नीषोमोत्पत्तिः
Agni–Soma Origin and the Brahmāgnīṣomīya Doctrine
उदयं ज्योतिषां शश्वत् सोमादीनां करोति यः । अन्तर्देहेषु चोदानं यं वदन्ति मनीषिण:
udayaṁ jyotiṣāṁ śaśvat somādīnāṁ karoti yaḥ | antardeheṣu codānaṁ yaṁ vadanti manīṣiṇaḥ ||
毗湿摩说道:那位恒常令诸光曜升起——以月为始——而智者于有身众生之内称之为名为“优陀那”(Udāna)的生命之流者;此力即所指之宇宙之风,主宰上升之动势,将内在的生息与外在天穹的秩序相系。
भीष्म उवाच
The verse links macrocosm and microcosm: the same governing principle that orders the rising of celestial lights is present within living beings as Udāna, the upward-moving vital force. It suggests an ethical-spiritual vision where understanding inner discipline (prāṇa) aligns one with cosmic order (ṛta/dharma).
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on higher knowledge and the foundations of order. Here he identifies a cosmic function—causing the luminaries to rise—and equates it with the internal life-current called Udāna, presenting a contemplative teaching on how universal forces operate within the body.
